    摘要: The invention relates to novel acetoacetylated diamines and polyamines and to a method for the production thereof. The acetoacetylated diamines and polyamines are compounds of formula (I), wherein R?1 and R2¿, independent of one another, represent hydrogen or C¿1-6? alkyl, and A represents C3-8 cycloalkanediyl or a group of formula (II): -(CR?3R4)¿p-[NR-(CR5R6)q]r .

    摘要: The invention relates to a method for producing α-dicarbonyl compounds of formula (I), wherein R?1 and R2¿, independently of each other, mean C¿1-6?-alkyl. Said method is characterised in that an α,ß-unsaturated ketone of formula (II), wherein R?1 and R2¿ have the meaning above and R?3 and R4¿, independently of each other, mean hydrogen, C¿1-6?-alkyl or di-C1-6-alkylamino, is reacted with ozone and the resulting ozonide is treated reductively.
